Extending or receiving short-term finance is part and parcel of running a small business. When you don’t need a full loan facility, a simple promissory note can be an efficient, legally recognised way to record a promise to pay a sum of money.
But templates floating around the internet can be risky if they miss key clauses or don’t suit Australian law. In this guide, we’ll explain when a promissory note makes sense, what a solid promissory note template should include, how to secure your position, and the steps to issue and enforce it the right way.
Our goal is to help you manage cash flow confidently and reduce the risk of disputes, so you can focus on growing your business.
What Is A Promissory Note In Australia?
A promissory note is a written, signed promise by one party (the “maker”) to pay a specific sum of money to another party (the “payee”) at a certain time or on demand. Think of it as a streamlined IOU that’s more formal and legally robust.
Under Australian law, promissory notes are recognised as negotiable instruments. To be enforceable, the document needs to clearly set out the promise to pay, the amount, who is being paid, and when. It also needs to be signed by the party promising to pay.
If you’re after a deeper dive into definitions, enforceability and common use cases, our detailed explainer on promissory notes in Australia is a good place to start.
How Is It Different To A Loan Agreement?
A promissory note is usually shorter and more payment-focused than a loan agreement. It records the debt and repayment promise, but may not include all the bells and whistles (like complex representations and warranties) that you’d expect in a larger funding deal.
If you’re advancing a more substantial sum, need staged drawdowns, or want comprehensive protections, a formal Loan Agreement (with either secured or unsecured terms) is often the better fit. You can still pair a loan or promissory note with extra security and guarantees (more on that below).
When Should A Small Business Use A Promissory Note?
Promissory notes work well in straightforward, short-term or one-off payment scenarios. Common small business uses include:
- Bridging finance between related entities or sister companies.
- Documenting a short-term advance to a supplier or reseller.
- Recording a debt after a settlement discussion, where the other party agrees to pay by a certain date.
- Converting an informal IOU into a clear written promise with interest and default consequences.
They’re also useful if you want a clean, self-contained document that can sit alongside other commercial paperwork. However, if you’re offering trade credit on an ongoing basis, it’s generally smarter to set up proper credit terms and Terms of Trade, and then deploy promissory notes selectively if a debtor falls behind or restructures their payments.
Quick tip: while a promissory note sets the obligation to pay, it doesn’t automatically give you rights over the debtor’s assets. If you want real protection, think about security and registrations (we’ll cover this shortly).
Promissory Note Template: Essential Clauses To Include
A strong promissory note template keeps things simple but complete. At minimum, you’ll want the following elements drafted in plain, unambiguous wording.
1) Parties And Amount
- Full legal names and ABNs (if applicable) of the maker (debtor) and payee (creditor).
- The principal amount in AUD, written in both numbers and words to avoid ambiguity.
2) Payment Terms
- When the debt is payable: on demand, a fixed date, or instalments on a schedule.
- How payments will be made: bank transfer details, reference requirements, and business days rule.
- Application of payments: to fees/interest first, then principal (if you want this priority).
3) Interest
- Interest rate (per annum) and how it’s calculated (simple vs compounding, daily vs monthly accrual).
- Default interest rate that applies if a payment is late (ensure it’s reasonable and not punitive).
4) Early Repayment And Prepayment
- Whether the maker can prepay without penalty, and how to apply prepayments (interest vs principal).
5) Default Events And Consequences
- Define events of default: missed payment, insolvency events, misrepresentation, or breach of the note.
- Consequences: acceleration of the balance (entire amount becomes due) and recovery of enforcement costs.
6) Security (If Any)
- If the note is secured, say so clearly and describe the collateral. In practice, security is documented in a separate General Security Agreement or other security document and perfected on the PPSR.
7) Guarantees (If Any)
- If you want directors or related parties to guarantee the debt, include a guarantee clause or use a standalone guarantee. Read up on the risks and obligations in our guide to personal guarantees.
8) Set-Off And No Deductions
- To keep repayments clean, include a no set-off clause so the maker can’t reduce what’s owed by alleging unrelated claims. For more complex arrangements, dedicated set-off clauses may be appropriate elsewhere.
9) Assignment And Transfer
- State whether the payee can assign the note (sell or transfer the debt) and whether the maker can transfer obligations (usually not without consent).
10) Notices, Governing Law And Jurisdiction
- How formal notices must be sent (email vs post), and which Australian state or territory law applies.
- Jurisdiction for disputes to keep enforcement local and efficient.
11) Execution
- Ensure the maker signs correctly. If a company is signing, follow the Corporations Act execution rules or use an authorised signatory approach consistent with your deed and execution practices. Wet-ink or electronic signatures can both work if your process is consistent and reliable.
Optional But Helpful
- Verification details: including ACN/ABN and registered office helps identify the debtor precisely.
- Costs and taxes: specify that the maker covers reasonable enforcement costs and bank fees.
- Severability and waiver: standard legal “boilerplate” to keep the note intact if one clause is invalid.
The best templates are simple, readable and adapted to your use case. If you expect any friction, it’s wise to tailor the note and pair it with security or guarantees.
Securing The Debt: Guarantees, PPSR And Alternatives
A promissory note by itself records the debt. To improve your chances of recovery, consider these add-ons.
Director Or Personal Guarantees
Where the maker is a company, a director guarantee can put personal skin in the game. Guarantees come with serious obligations, so both sides should understand what’s being promised. Our overview of personal guarantees explains common pitfalls and how to manage them.
Security Interests And PPSR
Security turns you from an unsecured creditor into a secured creditor with priority over specific assets. Typically, you’ll document this in a General Security Agreement (GSA) or asset-specific security, and then register it on the Personal Property Securities Register (PPSR).
If you’re new to this area, start with our plain-English overview of what the PPSR is and why registering your interest matters. When you’re ready, our team can assist you to register a security interest correctly and on time.
Alternatives: Trading Terms And Ongoing Credit
If you offer goods or services on account, don’t rely on one-off notes alone. Put in place robust Terms of Trade and a credit application with built-in security, guarantees, retention of title and default interest. You can still use a promissory note to restructure specific arrears while keeping your master terms in place.
How To Issue And Enforce A Promissory Note (Step-By-Step)
Here’s a practical workflow you can adapt for your business.
Step 1: Agree The Commercials
- Confirm the principal amount, timing (on demand, fixed date or instalments), and interest structure.
- Discuss whether a guarantee or security is required. If yes, draft the appropriate documents and plan PPSR registration.
Step 2: Prepare The Documents
- Generate your promissory note using a tailored template with the core clauses above.
- If you’re taking security, prepare your GSA or asset security and line up PPSR details (grantor name, collateral class, serial numbers where relevant).
- For guarantees, prepare a standalone guarantee and ensure each guarantor understands the obligations.
Step 3: Execute Properly
- Have the maker sign correctly. If a company, use valid company execution or an authorised representative. Keep executed copies and evidence of authority.
- If taking security, execute the security document at the same time.
Step 4: Register Security (If Applicable)
- Register your PPSR interest promptly. Timing can affect priority, so don’t delay.
- Double-check the details match the executed security document exactly to avoid an ineffective registration.
Step 5: Administer And Monitor
- Send a payment schedule and reminders before due dates. Apply payments as specified in the note.
- If a payment is missed, issue a default notice in line with your contract before escalating.
Step 6: Enforce If Needed
- Depending on your documents, you may accelerate the debt, claim default interest, recover reasonable enforcement costs, and (if secured) consider exercising security rights.
- If the parties agree to restructure or settle the debt, record it in a clear settlement document such as a Deed of Release and Settlement and update or discharge any registrations as required.
Practical Tips To Reduce Disputes
- Keep communications in writing: confirm any changes to amounts or timing by email and then update the note if needed.
- Be precise: confusion over interest calculations, due dates or “business days” is a common source of friction.
- Stay compliant: if you intend to charge default fees or automatic debits, make sure any late fee or direct debit processes comply with Australian law.
Common Mistakes To Avoid
- Using a vague template: missing repayment dates, unclear interest terms or no default mechanism weakens your position.
- Skipping security: if the debtor becomes insolvent, unsecured creditors are often last in line. Consider security or guarantees early.
- Bad execution: a note signed by the wrong entity or without authority can be hard to enforce.
- No follow-up: diarise due dates and act quickly if a payment is missed. Momentum matters.
FAQ: Can I Just Add “Security” Into The Note?
It’s cleaner to keep the promissory note focused on the payment promise and use a separate security document, especially if you plan to register on the PPSR. This avoids mixing concepts and makes enforcement clearer. If you are taking security, it’s important to understand how the PPSR affects your priority and why accurate registration is critical.
FAQ: What If We Want Instalments?
That’s fine-just be specific. Set the instalment amounts, due dates, how interest accrues between payments, and what happens if one instalment is missed (for example, triggering acceleration of the balance).
FAQ: Do I Need A Lawyer For A Simple Note?
You can draft a straightforward note yourself, but the stakes increase if the amount is material, there’s a risk of default, or you’re taking security or guarantees. In those cases, it’s best to get tailored documents prepared and your registrations handled correctly the first time.
Key Takeaways
- A promissory note is a simple, legally recognised promise to pay-great for clear, short-term debt arrangements between businesses.
- A solid template should cover parties, amount, payment timing, interest, defaults, assignment, governing law and proper execution.
- To improve recoveries, consider a director guarantee and document security separately with a General Security Agreement, then register on the PPSR using our security interest registration service.
- Use master Terms of Trade and credit terms for ongoing customers, and reserve promissory notes for specific debts or restructures.
- If a dispute arises or you agree to a revised repayment plan, record it cleanly-often via a Deed of Release and Settlement-and keep an eye on any PPSR implications.
- For larger sums or more complex arrangements, a tailored Loan Agreement may be a better fit than a basic note.
